[PATCH] Add --info-path and --man-path options to git.

[Jon Seymour <jon.seymour@xxxxxxxxx>]

To better support git extensions provided by 3rd parties
which would like to install their own man pages and Info files
in the same place as git's own man pages and Info files
add support for --man-path and --info-path options.
